Answer 1

$\huge\sf\pink{HEY\:USER}$

$\huge\sf\pink{ANSWER}$

$\implies\sf\blue{NUMBER\:OF\:ORANGES=6}$

$\implies\sf\blue{COST\:OF\:6\: ORANGES=20}$

Hence,

$\implies\sf\blue{COST\:OF\:Per\: ORANGES \frac{20}{6}=\frac{10}{3}}$

Now,

$\implies\sf\blue{SP\:OF\:4\: ORANGES=18}$

$\implies\sf\blue{SP\:OF\:PER\:ORANGES \frac{18}{4}=\frac{9}{2}}$

$cost<sp$

$\sf\pink{IT\:is\:a\:GAIN}$

Now,

$\text{Gain=sp-cp}$

$\text{Gain=\frac{9}{2}-{10}{3}}$

$Gain=\frac{7}{6}$

Now,

Gain%= 7/6÷10/3×100=35.

So,

The gain is 35%
